Vulnerability in Sails (CVE-2016-10549)

Summary

Vulnerability in Sails (CVE-2016-10549). Risk of unauthorized operations or information disclosure. Exploitable via allRoutes.

Original description

The description as published by the source.

Sails is an MVC style framework for building realtime web applications. Version 0.12.7 and lower have an issue with the CORS configuration where the value of the origin header is reflected as the value for the Access-Control-Allow-Origin header. This would allow an attacker to make AJAX requests to vulnerable hosts through cross site scripting or a malicious HTML Document, effectively bypassing the Same Origin Policy. Note that this is only an issue when allRoutes is set to true and origin is set to * or left commented out in the sails CORS config file. The problem can be compounded when the cors credentials setting is not provided. At that point authenticated cross domain requests are possible.
